Note to teacher: There are a number of factors which might make your projected image of the angles be slightly stretched. If this is the case the answers above will be unreliable. There is a protractor in the diagram which can be dragged over the angles. The green buttons will rotate the protractor. Right click over the diagram to zoom in in order to read the protractor accurately.

Note to teacher: Doing this activity once with a class helps students develop strategies. It is only when they do this activity a second time that they will have the opportunity to practise those strategies. That is when the learning is consolidated.
